Chicago Cubs star and former NL MVP Kris Bryant was pulled from Wednesday’s game against the San Francisco Giants due to an unknown injury.

Following the game, Bryant explained that he injured his knee during indoor batting practice in San Francisco. He also doesn’t seem to be too concerned about the injury.

But any time we’re talking about a player of Bryant’s ability and the knee, it has to be cause for alarm. Chicago needs Bryant at 100 percent moving forward if it wants to take the highly competitive NL Central and earn a playoff spot this season.

Bryant, 27, is hitting at a .299 clip with 20 homers, 49 RBI and a .406 on-base percentage. With an off day on Thursday, we’ll see how Bryant feels ahead of Chicago’s big weekend series against the Milwaukee Brewers.
